    In the Definition 1.2. (homotopy), the link to the example does not work properly:
    https://ncatlab.org/nlab/show/Introduction+to+Topology+--+1#ProductTopologicalSpace

    It could go for instance to the example 2.19 here:
    https://ncatlab.org/nlab/show/Introduction+to+Topology+--+1#TopologicalSpacesExamples

    or to the examples here:

    Thanks for the alert!

    The word “Binary” was missing in the anchor, it should have been

    Fixed now. Thanks.

    below the statement that every groupoid is equivalent to a skeleton I have added (here) the remark that equivalently every groupoid is isomorphic to a quasi-skeleton (a copoduct of delooping groupoids times codiscrete groupoids).
